Ciano Muy Líquido is a single-component cyanoacrylate adhesive with low viscosity and ultra-fast cure, ideal when you need the adhesive to penetrate narrow joints or porous surfaces before setting. It contains no solvents, reacts with ambient moisture and provides clean, strong bonds with no visible residue across a wide range of different materials.

What it is used for
Its low viscosity makes it the ideal choice when the adhesive needs to flow on its own into the joint, wicking through fine gaps, cracks or absorbent materials by capillary action. It is a standard tool in scale modelling workshops, special effects, prototyping, restoration and light industrial production.
- Bonding scale model parts with very thin or interlocking joints
- Repairing ceramics, porcelain and glass with clean breaks
- Bonding leather, rubber and gum in leathergoods or footwear
- Fixing small metal parts where capillary penetration is required
- Consolidating porous materials such as wood or plaster before sanding or painting
- Special effects and prosthetics workshops for bonding rigid materials
- Manufacturing and repairing prototypes and scale models
How to use it
- Clean both surfaces to be bonded: they must be dry, free of dust, grease or residue from other adhesives.
- Apply a minimal amount of Ciano Muy Líquido to one of the surfaces. Being very fluid, a few drops are sufficient; excess does not improve the bond and may cause staining.
- Join the pieces immediately and press firmly for a few seconds. Ambient moisture initiates curing instantly.
- Maintain pressure without moving the pieces until you feel the bond has set (typically between 5 and 30 seconds depending on materials and humidity).
- If you need to speed up the process or are working with low-porosity materials, apply Spray Acelerador de Ciano to the opposite surface before joining the pieces.
- Leave the part to rest without stressing the bond for at least 10–15 minutes to reach maximum strength.
- Close the container immediately after each use to prevent the adhesive from polymerising in the nozzle or inside the tip.
Caution: Cyanoacrylate bonds skin instantly. Always work with nitrile gloves or similar. If contact with fingers occurs, do not force separation: wash repeatedly with warm water and soap. Keep the product out of reach of children. Avoid contact with eyes; in case of splashing, rinse with plenty of water and consult a doctor. Do not inhale vapours in enclosed spaces — ventilate the work area.
Usage tips
Control the amount applied
With Ciano Muy Líquido, less is more. Being so fluid, it tends to spread by capillary action beyond the bonding area. Always apply the minimum amount needed, ideally with the nozzle directed towards the joint, and prevent the adhesive from overflowing onto areas you do not want to bond. Excess can cause white marks (blush) on porous materials or painted surfaces.
Temperature and humidity matter
Cyanoacrylate cures thanks to the moisture present in the environment and on the surface. In very dry conditions or at low temperatures, curing may be slower than usual. If you work in a low-humidity workshop, you can lightly breathe on one of the surfaces before applying the adhesive, or use the Spray Acelerador de Ciano to ensure immediate setting.
Storage and shelf life
The biggest enemy of any cyanoacrylate is the moisture that enters through the nozzle after each use. Wipe the nozzle with a dry cloth after each application, close the cap firmly and store the container upright in a cool, dry place away from direct sunlight. If the product has thickened in the nozzle, remove that part without shaking the bottle and do not insert objects into the opening, as they could contaminate the contents.
Frequently asked questions
What is the difference between a very fluid, normal and thick cyanoacrylate?
The main difference is viscosity. Ciano Muy Líquido is the most fluid: it penetrates by capillary action into very narrow joints and porous materials. Ciano Normal has a medium viscosity, suitable for most general applications. Ciano Denso is thicker, ideal for vertical surfaces or when you need the adhesive not to flow outside the application area. Choose according to the geometry and porosity of the parts.
Does it work on very smooth or non-porous surfaces such as glass or polished metal?
Yes, although on completely smooth and non-porous surfaces curing may be slightly slower because less moisture is available. In these cases you can apply Spray Acelerador de Ciano to one face to ensure near-instant setting and good final strength.
Can I use it to bond plastics such as ABS, PVC or polystyrene?
Very fluid cyanoacrylate is compatible with many plastics, including ABS, polystyrene and some types of rigid PVC. However, materials such as polypropylene (PP) or polyethylene (PE) have very low surface energy and do not bond well with any cyanoacrylate without prior treatment. Always do a test on a non-visible area before applying to the final part.
What do I do if the adhesive bonds my fingers together?
Do not try to pull your fingers apart by force: you could injure yourself. Wash the area repeatedly with warm water and soap, rubbing gently. Heat and moisture soften the cured adhesive. You can also use acetone (such as conventional nail polish remover) applied carefully. If bonding is severe or affects eyes or mucous membranes, seek emergency medical attention.
How long do you need to wait for the bond to reach maximum strength?
Initial grip occurs within seconds, but maximum strength is not reached until 10 to 30 minutes have passed, depending on the material, temperature and ambient humidity. For parts that will be subjected to mechanical stress, it is best to let the bond rest for at least one hour before loading it.
How do I remove cured cyanoacrylate residue from a surface?
Acetone is the most effective solvent for cured cyanoacrylate. Apply with a cloth or cotton swab to the hardened residue, wait a few seconds and remove carefully. Be cautious with plastics sensitive to acetone (acrylic, polystyrene) as it can damage the surface. On metals or glass you can also use fine cutting tools or fine-grit sandpaper once the adhesive has softened.
Is cyanoacrylate resistant to water and heat once cured?
Cured cyanoacrylate has moderate water resistance, sufficient for indoor applications and occasional exposure to moisture. However, it is not suitable for prolonged immersion or environments with temperatures continuously above approximately 80 ºC. For applications requiring greater thermal or outdoor resistance, consult other adhesive families in the Feroca catalogue.
Is there a semi-flexible version if I need the bond to absorb vibrations?
Yes. If you need the bond to have some elasticity to absorb vibrations or small movements, PERMABOND 2050 Ciano Semi-Flexible is the right choice. It offers the benefits of cyanoacrylate's fast cure with greater deformation capacity without the bond breaking.
